Theses and Dissertations--Kinesiology and Health Promotion

The purpose of this study was to increase understanding of factors associated with nonmedical anabolic steroid use among males ages 18-30 who do not participate in intercollegiate athletics. The Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was developed, reviewed for content validity by a jury of experts, and pilot tested. The pilot testing results (n=25) demonstrated acceptable reliability (Cronbach’s alpha= 0.74). The final version of the Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was administered at two distribution sites which included Ford’s Fitness Center in Lexington, Kentucky and …

Approach-Iron Play In High Performance Golf: From Testing To Tournament Play, Samuel John Robertson

Theses: Doctorates and Masters

The capability of a golfer to record a low score depends upon well-developed abilities in each of the recognised on-course skill components (driving the ball off the tee, hitting approach-iron shots, hitting short-iron shots and putting). Despite approach-iron play being considered perhaps the most important and definitely the most practiced skill in the game, the ability to quantify the golfer’s ability to hit approach-iron shots in a controlled, off-course environment (eg. training) cannot yet be undertaken due to the lack of appropriate assessments. Such tools have considerable potential for use in both the field and in research for implementation in …

The Influence Of External Loading And Speed Of Movement On Muscle-Tendon Unit Behaviour And Its Implications For Training, Jacob Earp

Theses: Doctorates and Masters

In this thesis great emphasis has been placed on vastus lateralis (VL) muscle-tendon unit (MTU) structure, behaviour/movement and adaptation. Of particular interest was how external loading and movement speed influence these variables. In the first study (Chapter 3) we developed a new methodology by which electromyography (EMG) could be normalised during large range of motion knee extensions. This methodology was then used as part of a larger study, which investigated how external loading influenced the interaction of muscle and tendon (MTU behaviour) during stretch shortening cycle isoinertial knee extensions, and how muscle activity and intrinsic tendon force (Ft) influenced MTU …

The Development And Evaluation Of A Testing Protocol To Assess Upper Body Pressing Strength Qualities In High Performance Athletes, Kieran Young

Theses: Doctorates and Masters

PURPOSE: The purpose of this study was to evaluate the reliability of an isometric force assessment (isometric bench press) across 4 standardised angles and an isoinertial force and velocity assessment (ballistic bench throw) utilising a relative load based on a percentage of one repetition maximum (1RM) in the bench press; and to evaluate whether the use of the dynamic strength deficit (DSD) ratio can guide training and detect changes induced by training over a 5 week period.

METHODS: Twenty four elite male athletes (age = 19.9 ± 2.7yrs; mass = 79.1 ± 13.0kg) performed the isometric bench press and a …

Exploring Predictors Of Sport Commitment In Coaches, Erin Bormann

Theses: Doctorates and Masters

The Sport Commitment Model (SCM) has been used to gain insight about the factors that influence people’s decision to continue participation in sport. Majority of the studies that are grounded in the SCM have been conducted with athletes. To date, few studies have examined sport commitment of coaches however, these did not assess two commitment dimensions per se (functional or “want to” and obligatory or “have to” commitment to sport), rather each has measured certain predictor variables and inferred commitment dimensions based on clustering of predictors [i.e. 13]. This study had one main purpose, to examine the SCM amongst coaches. …

Neuromuscular Fatigue And Biomechanical Alterations During High-Intensity, Constant-Load Cycling, Amanda Julie Overton

Theses: Doctorates and Masters

Neuromuscular fatigue is an inevitable process at play during prolonged exercise, and may be caused by multiple alterations within the central nervous system and peripheral musculature. As fatigue develops, the neuromuscular system must adapt to these changes by making compensatory movement pattern adjustments so as to use motor pathways that are less fatigued in an effort to maintain task performance; motor variability is thus increased. The primary purpose of the four studies contained within this doctoral thesis was to detail the progression of exercise-induced neuromuscular fatigue, and to improve our understanding of the muscle activation and joint kinematic alterations that …

Effects Of Pulsed Electromagnetic Field Therapy On Symptoms Associated With Eccentric Exercise-Induced Muscle Damage, Henry Banyard

Theses: Doctorates and Masters

Unaccustomed exercise consisting of eccentric contractions induces muscle damage that is characterised by muscle weakness, soreness, swelling and increased muscle stiffness. These symptoms affect daily activities and athletic performance; therefore, interventions to attenuate the symptoms and enhance recovery from muscle damage are necessary. Pulsed electromagnetic field therapy (PEMFT) is anecdotally reported to increase muscle blood flow and oxygenation to enhance tissue healing. One previous study showed that PEMFT was effective for alleviating muscle soreness and losses in range of motion after exercise. However, studies investigating the effect of PEMFT on recovery of muscle strength following eccentric exercise are lacking. The …

Adolescent Athletes With Type 1 Diabetes: Experiences With Continuous Subcutaneous Insulin Infusion, Regina Tow

UNF Graduate Theses and Dissertations

Adolescent athletes with type 1 diabetes (T1DM) face unique challenges when compared to peers with and without diabetes. Continuous subcutaneous insulin infusion (CSII) provides a method of insulin delivery that can enhance flexibility in insulin regimens and lifestyle that may be especially appealing to the adolescent athlete. No studies have explored the impact of athletics in this population. This descriptive qualitative study explored and described the experiences of adolescent athletes using CSII as their primary insulin delivery method, with a focus on athletic participation and performance.

The purposeful sample consisted of four adolescent athletes, ages 13 to 15 years with …

Comparing Aerobic Adaptations With A Running Based High Intensity Interval Training (Hiit) And A Continuous Endurance Training (Cet) Protocol In Relatively Healthy Adults, Efrain James Sanchez

EWU Masters Thesis Collection

"The purpose of this study was to compare a running based High Intensity Interval Training (HIIT) protocol to a Continuous Endurance Training (CET) and their aerobic adaptations, such as increased VO₂[subscritp max] and improved body composition. Recruitment of participant's occured by flyers on campus. After indicating interest, volunteers answered no, to all questions on the PAR-Q to be eligible. Pre and post testing included a submaximal VO₂[subscritp max] test, using the 12 min cooper run test, and body composition using the BOD POD GS (COSMED USA Inc., Concord, California). After testing, the participants were randomly stratified based on matched aerobic …

Assessment Of Balance In Collegiate Cheerleaders: Is Implementing A Balance Training Program A Good Idea?, Caitlin Carroll

Honors Theses

Cheerleading has evolved immensely over the years. Gone are the days of simply shaking pom poms and yelling "GO TEAM!" Flips, twists, and prime athletic ability are what can be seen on the sidelines of any collegiate football or basketball game. Cheerleaders in general are assumed to have an above average level of balance, due to the nature of their training and sport. However, with these new skills comes the increasing risk for injury, and this risk may differ according to a cheerleader's position. As with any sport, cheerleading has specific positions. The cheerleaders that are put into the air …

The Effect Of The Female Athlete Triad On Performance: Both Physiologically And Psychologically, Constance Darlington

Honors Theses

The female athlete triad is a condition that is composed of an interaction of three separate disorders: low energy intake due to the presence of an eating disorder or disordered eating, menstrual dysfunction, such as, oligomenorrhea or amenorrhea, and osteoporosis. Separately, each disorder can affect performance; however, when the disorders are combined, the consequences are magnified. The female triad has a profound effect on an athlete's performance both physiologically and psychologically. The female athlete triad can affect any female athlete; however, it is more prevalent among the athletes that specialize in aesthetic sports or sports that emphasize leanness, for example, …

Analytical Research Topics In Sport Management, Gi-Yong Koo

Graduate Theses and Dissertations

The field of sport management has grown tremendously as an academic discipline. Researchers have continuously discussed the scope and direction of research and the importance of the diversity of research design. There have been a significant number of studies examining the scope and direction of research over the past few decades such as: the lack of diversity in methodology; the lack of diversity in research focus; the lack of importance of power analysis; and the lack of diversity in topic areas. Embracing a variety of research designs is an absolutely necessary condition for the growth and credibility of sport management …

Construct-Validity Of The Engagement With Challenge Measure For Adolescents: Structural- And Criterion-Validity Evidence, E. Whitney G. Moore, David Hansen

Kinesiology, Health and Sport Studies

For adolescents, engaging with challenge is a key developmental task, hypothesized to support development of adult-like competencies (e.g., agency and self-direction; Larson, 2000). This study aimed to assess the construct-validity (structural- and concurrent-validity) of a new self-report measure assessing adolescents’ engagement with challenge to help researchers understand how different settings and the conditions in these settings support adolescents’ development. The sample consisted of 337 adolescents in 10 FFA programs along with the adult advisors in each program. Adolescents completed a questionnaire, which included the Engagement with Challenge measure and the following criterion variables: number of contests completed, participation frequency, and …
